I was just wondering, I know there are several ways to prep rusty areas before filler is applied. On a sandblasted surface, which is best - acid wash or etching primer, or is there much difference? I'm getting ready to work the body over on a 54 Chevy. I't has some rust issues around and under the stainless. Non of it has gone though yet, and I'd like to know the best way to stop rust dead in it's tracks, where skim-coats of plastic filler are used.
All the limited body work I've ever done, I've always applied the plastic directly to clean, dry bare metal. I never had any problems but then, I only kept those cars for 5 years average. I'd like to do the 54 as best I can.
I didn't mean to answer your question with another question, but this seemed like a good place to ask - thanks
